Not going to lie, this is one of the most disappointing and generic waves for an original IP LEGO theme I've seen in years.
Let's start off with 72006, Axl's main vehicle. It's basically a miniature Fortrex that's been infected with a terrible color scheme and stupid add-ons. The worst part about it is that the original Fortrex will probably still be around at retail stores during the 2018 wave, making this thing's existence extremely unnecessary.
Then we've got 72003. It's definitely the best in the batch, but that's not exactly saying much. Sure, it's an okay fighter jet-like spaceship, but is it better than similar sets LEGO has done in the past? No, not really. I might even go as far as to say that it's one of the most generic and boring spaceships we've ever seen in a LEGO Space (or in this case, Space-like) theme.
Moving on to 72002, it's your average LEGO motorcycle set. Nothing special, nothing new. Nothing. It's just a box of nothingness.
I'm not too sure on what I can say about 72001 since the bulk of the set (Lance's vehicle) is covered with the usual confidentiality watermark and the leaked set name doesn't help either. So in other words, I have no idea what it is. It kind of looks like a turret with lances glued on maybe? All I know is that it looks like a cobbled together mess.
We're at the second to last set, 72005. It's Aaron's vehicle and probably his worst. I don't have much to say here. It's just an ugly plane with an even uglier color scheme.
Finally, there's 72004, Clay's vehicle. Nexo Knights has had some of the best mechs in recent LEGO history, but this one is by far the weakest of the five or six released. It's a cobbled together mess with a trans. orange obsession. The gimmick of having a mech inside of a mech is alright, but it was just not done well.
